cant store returned values from ajaxJSON function

[Paul_Ramcharitar]

Hi this is my ajaxJSON function:

Code: Select all

ajaxJSON({ 
	  url: "/php/sig_image_store.php",
	  params: {
		sig: bmpString,
		name: imageName
	  },
	  method: "post",
	  async: true,
	  handler: infoHandler
	});

This if my infoHandler function:

Code: Select all

function infoHandler(obj) {
    alert("Result: " + obj.data);
    if(obj.data != 'success'){
		changeElementValue("sigSaveId",'N');
	}else{
		changeElementValue("sigSaveId",'Y');
	}
	alert(get('sigSaveId'));	
}

I'm trying to assign a text field with id "sigSaveId" with the value "Y" or "N"

The ajax request is successful. it sends back obj.data with "success". But when i try to assign obj.data or any variable within the infoHandler function, nothing gets assigned.

Help please.

What type of widget is "sigSaveId"?

[Paul_Ramcharitar]

Its a hidden Textbox widget. I know for some reason, "changeElementValue" doesn't work on dynamic output fields, but they work on input fields like textboxes.

I coded up your example, almost exactly as you posted it, and did not have any trouble, it worked perfectly for me.

Here's the RPG I used:

Code: Select all

     H DFTACTGRP(*NO)

     FTESTD     CF   E             WORKSTN EXTFILE('SKTEST/TESTD')
     F                                     HANDLER('PROFOUNDUI(HANDLER)')

     C                   exfmt     testd1
     C     sigSaveId     dsply
     c                   eval      *inlr = *on 

Here's the display file I used:

Code: Select all

     A                                      INDARA
     A          R TESTD1
     A                                  1  2HTML('QPUIREC0    ')
     A                                  1  3HTML('{"screen":{"record format nam-

     A            BTNRTNRPG      1A  H
     A            SIGSAVEID     10A  H 

And he'res the JavaScript I used to make it work

Code: Select all

var ScottKlement = { }

ScottKlement.paulAjax = function() {

  ajaxJSON({
     url: "/ScottTemp/paulJson.txt",
     params: {
      sig: "sig here",
      name: "image name here"
     },
     method: "post",
     async: true,
     handler: ScottKlement.infoHandler
   });

} 

ScottKlement.infoHandler = function(obj) {
  alert("result; " + obj.data);
  if (obj.data != 'success') {
	changeElementValue("sigSaveId", 'N'); 
  } else {
	changeElementValue("sigSaveId", 'Y'); 
  }
  alert(get('sigSaveId'));
}

This worked perfectly for me

[Paul_Ramcharitar]

Hi Scott, the way how you did the javascript with the structure, worked for me as well. I'm not sure why, lol

Thanks a lot for your help.
